I wonder if the "diversity" types ever think about what winning would look like.

If the whole globe is completely "diverse", doesn't that make the whole globe completely homogeneous?

I think the people seeding the idea know that, and they really don't want diversity the way the word is commonly understood. They want everything to be uniform, homogeneous urban monoculture.

For one thing, it makes totalitarian collectivism easier to implement. Just herds of brain-dead NPCs, parroting the same talking points from the same propaganda outlets, unquestioningly obeying for "the common good", always ready to agitate for the cause du jour, totally dependent on the social structure and unable to survive any disruption of the status quo.

They're also moral relativists, so they're desperate to eliminate the possibility of different cultures in different places. Easy observation of the fact that some cultural patterns have good results and some have bad results undermines their belief system. Can't have the peasants seeing greener grass next door, like how simple it is to dramatically reduce crime in El Salvador, and demanding those policies in their neighborhood.
